[QUOTE="Marc, post: 118922, member: 1638"] It is funny! Been told all along to use 1B, week before my 302; "biggest plus 40% of rest"! As for verifying polarity, I wouldn't fancy energising an installation with incorrect polarity! I don't know if the way the leads are connected affects whether or not the lights come on on the tester, but given they too can be connected the wrong way then you run the risk of having the centre contact of an Edison lampholder being the neutral (only one example). I suppose there are thousands of people up and down the country all taught one way or the other! [/QUOTE]
